VACUUM CLE' W:

Application filed March 20, 1922. Serial No. 545,060.

i the accompanying drawings.

The application relates to vacuum cleaning apparatus and refers more particularly to the portable type provided with a handle and also with a suction tool directly connectedto the fan casing.

One of the objects of the invention is: to provide a simple form of handle lock for olding the handle from rotation relative to the casing of the vacuum cleaner when the handle extends substantially horizontal or parallel to the longitudinal axis of this Otl er objects of the invention reside in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings:

Figure 1 is a side elevation of a vacuum cleaner embodying my invention; Figure 2 is a bottom plan view thereof.

The vacuum cleaner has the motor casing 1, the fan casing 2, and the suction tool -or nozzle 3 and is supported by the rolls 4 near opposite ends-of the suction tool, and the castor wheel 5 near the rear end of the motor casing 1.

For moving the fioor, it is provided with the handle 6 which carries the dust bag 7 connected to the tangential tubular outlet 8 of the fan casing 2. Ordinarily, the rotative position of the handle varies when the latter is in use upon the floor, but when the vacuum cleaner is not in use, it is preferred to keep the handle in substantially vertical positlon. Also, when the. vacuum cleaner is being used in raised position, it is desirable to retain the handle substantially horizontal or parallel to the axes of the motor andfan casings. In detail, the handle has the tubular portion 9 and the bifurcated inner end portion 10, the bifurcations 11 embracing and being pivotally connected to diametrically opposite sides of the forward end of the moto the pivot vacuum cleaner over the tor casing 1, as at 12. One of the bifurcations 11 has the head 13, the end of which is notched as at 14 and 15, the notches being beyond the pivot 12. 16 is a tempered resilient latch detachably secured to the rear face of the casing 2 as by means of the screws 17 and having the head 18 opposite 12 for alternative engagement in the notches 14 and 15 for respectively and horizontal positions. The ortion of the face of the head interme iate these notches is slidable over the head of the latch so that the intermediate positions of the handle may-be varied when in use. However, the portions of the face of the head beyond these notches are not slidable over the bead so that the bead determines the extreme positions of rotative adjustment of the handle relative to the motor-and fan casings. To positively hold the handle in a position substantially parallel to the axes of the motor and fan casings so that the casings cannot accidentally swing relative to the handle when the latter is supporting the former, there is the slide lock 19 mounted upon the lower side of the tubular portion 9 of the handle at the junction of the bifurcations 11 and ada ted to be moved beneath the bottom of t e motor casing 1 near its rear end. With this arrangement, it is seen that with the handle extending substantially parallel to the axes of the motor holding the handle in substantially vertical and fan casings and with the lock 19 extended, rotation of the handle in one direction relative to the casings is limited b the slide lock abutting the lower face a? the motor casing, while rotation in the other direction is limited by the latch.

What I claim as my invention is:

1. In a'vacuum cleaner,-the combination with a casing, of a handle pivotally connected thereto, a latch engageable with said handle when the same is extending parallel to the longitudinal axis of said casing to prevent rotation of said handle in one direction, and a sliding lock upon said handle and engageable with the lower wall of said casing when said handle is extending parallel to the longitudinal axis of said casing to prevent rotation of said handle in the opposite direction.

.5 is disposed parallel to the longitudinal axis of said casing for preventing rotation of said handle in one direct-ion relative to said casing, and

means engageable with said handle for preventing rotation of said handle in the opposite direction when disposed lo in said positi In testimo hire,
